Dirty air ducts can cause allergies as well as stale odors in your home. Over time, pollutants, mold and bacteria from dirt, pollen, tobacco smoke, pet hair and dust mites collect in the duct work of your home heating and cooling system. Every time your furnace or air conditioner is turned on, these particles are blown through the vents and spewed into the air you breathe. 

COULD YOUR HOME BE MAKING YOU SICK??? - Indoor air pollution is now listed by the Environmental Protection Agency as the forth-greatest environmental threat to Americans. One of the favorite places for indoor molds to grow is within the heating and air conditioning system and ductwork. These mold spores can cause eye irritation, runny nose, sore throat, sneezing, nasal and sinus congestion, and more.
